' 3 claims. (o1. 23e-36) v This invention relates to steel hose jointsand is more `particularly addressed to the provision of a steel hosejoint which is freely iiexible under working pressure, and one that isnot limitedto'the amount of flexibility. I

Another object of this invention is to provide a steelhose joint whichincludes a simple means for packing the joint and which is soconstructed'as to make easy access to the packing .Without necessitatingthe removal ofthe hose from the working position.

Another object of this invention is to provide a steel hosek jointincluding a long, wide construction in which there is provided a fluidlchamber for handling fluids of abrasive character under high pressureto minimize the possibility of the turbulent flow of the abrasive fluidunder pressure while passing through such steel hose joint.

tion it is believed will be apparent from the following detaileddescription of a preferred embodiment thereof as illustrated vin theaccompanying drawing:

In the drawing:

Figure 1 is `an elevation partly in mid-section of a steel hose jointembodying this invention.

Figure 2 is a side elevation thereof. v Figure 3 is a section takensubstantially o the line 3 3 of Figure 1.

In the preferred embodiment of my invention illustrated in theaccompanying drawing, 1 indicates a pipe or section of a steel hose towhich lthere is threaded a connecting member 2.` The connecting member 2is providedV4 with two spaced branches 3 and 4 forming a Y. Passages 5formed through the branches 3 and 4 of the connecting member 2 combinedhave a crosssectional area in excess of the cross-sectional areaof thepipe 1 permitting a substantially unrestricted flow of fluid through theconnecting member.

As the steel hose connecting member or joint embodying my invention isprimarily designed for the purpose of handling abrasive fluids such, forexample, as rotary well drilling mud and which mud is passed throughsuch `a steel hose under relatively high pressure, I have found it,desirable to provide a means in` such a coupling member for reducing toa minimum the turbulence of flow of such abrasive uid under highpressure as it is passing through the steel hose. In order to minimizethe turbulence of flow `through the connecting kmember or joint as the'iiuid is passing through in the` direction of ar- Other objects andadvantages of this inven UNITED STATES" PATENTOFFICE)t row 6; I` `formthe coupling member 2 with an inverted dome 7 which is cast integral-with the, coupling member 2 and provides a fluid cham-` ber in thecoupling member 2, j

' The ends of the branches 3 and 4 are pro` vided with transverselyflanges 8. The annular flanges are `provided with cupped annularshoulders 19 vinto which a .cup packing -10 is mounted around the-periphery of the angesr. Swivelled to the branches V3 and 4 are spacedcoupling members 114 and `12. The coupling members 11 and 12 areprovided with substantially cylindrical heads 13 provided on their innerperiphery with inwardly extending annular packing flanges 14 which ex-`tend inwardly to provide packing shoulders 15 extending annular Y whichretain a packing 10 k on the cupped shoulders 9L j The annular anges 8 twithin the cylindrical heads 13 of the coupling members 11 and'12 andare retained in position by means of trans.

versely extending swivel bolts 16 which extend axially through theannular flanges 8 and thev circular head 13. The bolts are `provided ontheir inner ends with nuts 17 which are screwthe bolts 16 are cupped`packinggrooves 21 into which cupped packing V22 is mounted. Packingfollowers 23 are positioned over the cupped packing grooves in positionto retain thepacking 22 in position. f

In order to provide for the expansion of the packing 10 and the packing22 by the pressure of the fluid passing through the joint, the flange 14is ported at a plurality of points around the packing 10 asA indicatedat 24, and the packing follower 23 is ported at av plurality of pointsaround the packing 22 as indicated at 25. Ports 24 and 25 are in l"opencommunication at their outer ends with the passage 26 of the couplingmembers lland 12 and with the passage 5 formed through the branches 3`and 4.

The outer ends of the coupling members 11 and 12 are threaded asindicated at 27 to receive connecting pipes 28. The` two pipes'27 rareconnected togetherV in any suitable manner such, for example,`as bymeansofuapair of e1- shown, but Well understood in the art, so thaty thebranches 11 and 12 of the joint may be connected with the steel hose. Itis not deemed necessary to speciiically illustrate the points describedin this kind oficonnection as it is Well understood in the art;

An important feature of my invention lies in the means provided for theadjustment of the packing utilized for making a fluid-tight jointwhether the packing be of the cup type illustrated at 10 and 22 or ofsome other form. The bolts 16 and nuts 17` provide means forindependently adjusting the packing for each of the branches 4 and 5 andare rin positions easily accessible so that these adjustments may bereadily made without interfering with the operation of the joint. v Y

Having fully described my invention, it is to be understood that I do.not wish to be limited to the details herein set forth, but my inventionis of the full scope of the appended claims.
